A von Neumann type inequality for an annulus
نویسندگان
چکیده
Let A r = { < | z 1 } be an annulus. We consider the class of operators F : T ∈ B ( H ) 2 − ⁎ + ≤ , σ ⊂ and show that for every bounded holomorphic function ϕ on sup ∞ where constant is best possible. do this by characterizing calcular norm induced as multiplier a suitable space .

15 صفحه اولA new inequality for the von Neumann entropy
Strong subadditivity of von Neumann entropy, proved in 1973 by Lieb and Ruskai, is a cornerstone of quantum coding theory. All other known inequalities for entropies of quantum systems may be derived from it. Here we prove a new inequality for the von Neumann entropy which we prove is independent of strong subadditivity: it is an inequality which is true for any four party quantum state, provid...
متن کاملLimits of finite graphs, Von Neumann algebras and a Cheeger type inequality
We prove that for any weakly convergent sequence of finite graphs with bounded vertex degrees there exists a limit graphing and thus an associated Type-II1 von Neumann algebra. The Kesten-von Neumann-Serre spectral measure of the Laplacian on the limit graphing is the weak limit of the spectral measures of the Laplacians of the finite graphs. Using this limit techniques we prove a Cheeger type ...

There is a Banach algebra satisfying the von Neumann inequality for polynomials in a single variable, without constant term, which is not isomorphic to a norm-closed algebra of operators on a Hilbert space.
متن کاملFinite Generation Type Properties for Fuchsian Group Von Neumann Algebras
In this paper we prove the existence of finite systems G of generators, with special properties, for the von Neumann algebras L(Γ)⊗B(H), obtained by tensoring the group von Neumann algebra of a fuchsian group Γ with the bounded linear operators on a infinite dimensional, separable, Hilbert space H . The results show that the linear span of ordered monomials that are products of powers of adjoin...
